Projected improvement is 100%

I am having some issue hope i can find any fix/resolution here. My vmware infrastructure utilization is really low around 40% overall, but not sure why its showing 100% on all of the servers in projected improvement view. Sharing screenshots here. hope anyone have any idea about it .

What is your HA setting in vCenter? If your infrastructure is close to a point where you are not meeting those constraints you may see 100% UI even after improvements. In this case there would typically be a recommendation to provision a new host as well.
